Remove Specific Category From Category Menu programmatically in Magento 2

Hello Friends!!!

In this blog, we are going to learn how we can remove a specific category from the category menu at the frontend.

Here, in the following example, I have added a filter of category name to remove from the menu.
I have created a preference for the class Magento\Catalog\Plugin\Block\Topmenu
Please follow the below steps to achieve the desired result.

Step1: Create di.xml file inside the app/code/Webkul/CustomModule/etc/ directory.

<?xml version="1.0"?>
<!--
/**
 * Webkul Software.
 *
 * @category  Webkul
 * @package   Webkul_CustomModule
 * @author    Webkul Software Private Limited
 * @copyright Webkul Software Private Limited (https://webkul.com)
 * @license   https://store.webkul.com/license.html
 */
-->
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:ObjectManager/etc/config.xsd">
    <preference for="Magento\Catalog\Plugin\Block\Topmenu" 
        type="Webkul\CustomModule\Plugin\Catalog\Block\Topmenu"/>
</config>

Step2: Now, create the Topmenu.php file inside the app/code/Webkul/CustomModule/Plugin/Catalog/Block/ directory.

<?php
/**
 * Webkul Software.
 *
 * @category  Webkul
 * @package   Webkul_CustomModule
 * @author    Webkul Software Private Limited
 * @copyright Webkul Software Private Limited (https://webkul.com)
 * @license   https://store.webkul.com/license.html
 */
declare(strict_types=1);

namespace Webkul\CustomModule\Plugin\Catalog\Block;

use Magento\Catalog\Model\Category;
use Magento\Framework\Data\Collection;
use Magento\Framework\Data\Tree\Node;
use Magento\Catalog\Model\ResourceModel\Category\StateDependentCollectionFactory;

/**
 * Plugin for top menu block
 */
class Topmenu extends \Magento\Catalog\Plugin\Block\Topmenu
{
    /**
     * @var StateDependentCollectionFactory
     */
    private $collectionFactory;

    /**
     * Initialize dependencies.
     *
     * @param \Magento\Catalog\Helper\Category $catalogCategory
     * @param StateDependentCollectionFactory $categoryCollectionFactory
     * @param \Magento\Store\Model\StoreManagerInterface $storeManager
     * @param \Magento\Catalog\Model\Layer\Resolver $layerResolver
     * @return void
     */
    public function __construct(
        \Magento\Catalog\Helper\Category $catalogCategory,
        StateDependentCollectionFactory $categoryCollectionFactory,
        \Magento\Store\Model\StoreManagerInterface $storeManager,
        \Magento\Catalog\Model\Layer\Resolver $layerResolver
    ) {
        $this->catalogCategory = $catalogCategory;
        $this->collectionFactory = $categoryCollectionFactory;
        $this->storeManager = $storeManager;
        $this->layerResolver = $layerResolver;

        parent::__construct(
            $catalogCategory,
            $categoryCollectionFactory,
            $storeManager,
            $layerResolver
        );
    }

    /**
     * Get Category Tree
     *
     * @param int $storeId
     * @param int $rootId
     * @return \Magento\Catalog\Model\ResourceModel\Category\Collection
     * @throws \Magento\Framework\Exception\LocalizedException
     */
    protected function getCategoryTree($storeId, $rootId)
    {
        /** @var \Magento\Catalog\Model\ResourceModel\Category\Collection $collection */
        $collection = $this->collectionFactory->create();
        $collection->setStoreId($storeId);
        $collection->addAttributeToSelect('name');

        ////add category name filter////
        $collection->addAttributeToFilter('name', ["neq"=>"Shoes"]);
        ///////
        
        $collection->addFieldToFilter('path', ['like' => '1/' . $rootId . '/%']); //load only from store root
        $collection->addAttributeToFilter('include_in_menu', 1);
        $collection->addIsActiveFilter();
        $collection->addNavigationMaxDepthFilter();
        $collection->addUrlRewriteToResult();
        $collection->addOrder('level', Collection::SORT_ORDER_ASC);
        $collection->addOrder('position', Collection::SORT_ORDER_ASC);
        $collection->addOrder('parent_id', Collection::SORT_ORDER_ASC);
        $collection->addOrder('entity_id', Collection::SORT_ORDER_ASC);

        return $collection;
    }
}

Now, look into the first image in which category Shoes is being displayed in the menu. And in the second image, the category Shoes is removed from the menu.
